TERMINAL-CLIP CON NECTER.

Application filed July 27, 1922. Serial No. 577,856

To all whom it may concern:

Be it known that I, JosnrH H. BnEAzNnLL. a citizen of the United States,residing in the city of New York, borough of Brooklyn, in the county andState of New York, have invented a certain new and useful Improvement inTerminal-Clip Connecters, of which the following is a specification.

The invention relates to clips for connecting wire terminals to theposts of s arkplugs and the like, and the object o the invention is toprovide a simple, economically manufactured spring clip by which thewire may be easily and quickly attached to and detached from the post,and which in the attachedcondition will hold reliably and maintain thedesired electrical contact efficiently.

The invention consists in certain novel features and details ofconstruction by which the above objects are attained, to be hereinafterdescribed and claimed.

The accompanying drawings form a part of this specification and show theinvention as it has been carried out in practice.

Figure 1 is a side elevation of a referred form of the improved clipattac ed to a sparkplug. 4

Figure 2 is corresponding plan view.

Figure 3 is a section taken longitudinally of the clip between its jaws,on the line 3-3 in Figure 2.

Figure 4 is a rear elevation corresponding to Figure 3.

. Figure 5 is a section on an enlarged scale, taken through the jaws ofthe clip and the inclosed post.

Referring to Figures 1 to 4 inclusive, 10 is the screwthreaded post ofwhich the terminal wire 11 is to be attached, shown as art of asparkplug 12 but which may be a inding-post or any like screwthreadedmember.

The clip is shown as'formed in a single piece from sheet metal,preferably spring brass, stamped and shaped by suitable dies to the formshown. It comprises an open cylindrical body 13 having spring jaws 14extending side by side therefrom, each formed with a semicylindricalbend 15, which bends are arranged oppositely to produce an open socketbetween them 1n which the post 10 is grasped and inclosed. The jawsextend beyond the bends and are curved outwardly and oppositely as at 16to .taut tobring the insulated facilitate engagement with the post byfor- Clbly spreading and guiding'the jaws in the operation ofapplying'the clip.

An important feature of the invention resides in the means for insuringreliable engagement of the jaws 14 with the post. This is effected bytapping or otherwise producing internal screwt ireads in the bends thepost and resist effectually any strains tendingto move the clip axiallyof the post while permitting the clip to rotate or oscillate thereon toan extent required by the relative position 0 the terminal wire to thepost. From the up er edge of the closed rear side ct the b0 y 13 extendsa branch 17 having oppositel extended curved wings 18 adapted to be cutaround the insulated terminal of the wire 11 and partially inclose itina firm grip. On the rear face of the body 13 is formed an internalgroove 19, and near the upper edge isan opening 20 in axial alinementwith the terminal wire, and at the rear lower edge of the body is anotch 21.

.The Wire 11 is attached to the clip by removing a short section of theinsulation to exposea length of the core-wires which are then threadedthrough the opening 20 to the inner face of the body 13 and drawnportion within the wings 18 which are then bent closely thereupon; thecore wires are drawn tightly through the notch 21 and lie partially inthe groove 19 and are then bent/sharply back to lie below the wings.Thus attached the engagement is reliable and electric contact insured. Adrop of solder may be applied to the core wires in the groove or at anyconvenient point if desired.

Although the spring jaws are described as tapped to match the standard.threads of the post and to be applied to the latter in place of theusual nut, it will be understoodthat the post may be specially formedwith a series of annular grooves and the jaws correspondingly formed tomatch thereto; the screwthreads of the post and jaws perform no functionother than a means of engagement by which movement of the jaws Qlongitudinallzeof the post is tgrevented, and l being formed with aninternal groove, and
